Comfy, not frumpy knickers

I've got a large selection of pretty rubbish knickers - lots with holes in them, a bit saggy, greying, mostly standard ones from M&S. I've decided to invest in some decent knickers that are both comfy and make me feel not totally frumpy (if not actually glamorous ..!). So far I've got some from Fatface which I love. Any suggestions of other places to look? Thanks!

I had a drawer full of grey , holey m&s knickers that I have recently bid farewell to. I got some multipacks from H&M- a mixture of shorties , lace trim and bikini . They are soft and nice colours , I like them !
